You will be given a definition of a task first, then some input of the task.
You are given a sentence in English. Your job is to translate the English sentence into Japanese.

Nearly all of these proteins can be explained by a single gene family, so this means that the diversity of silk types we see today is encoded by one gene family, so presumably the original spider ancestor made one kind of silk, and over the last 380 million years, that one silk gene has duplicated and then diverged, specialized, over and over and over again, to get the large variety of flavors of spider silks that we have today.
Output:
このタンパク質のほとんどは単一の遺伝子族でできていますこれは現代の多様な遺伝子が全て単一の遺伝子族の中に組み込まれていることを意味しますおそらくはクモの原種は１種類の糸しか作っていなかったと考えられます ３億８千年の進化の過程で糸の遺伝子が複製され分岐し特性を持つ糸ができるプロセスが何度も繰り返されて現在存在する非常に多様な種類が生成されるに至ったのです
